Not to be confused with the Red-crowned Parakeet (Pyrrhura roseifrons) from South America.

The Red-crowned Parakeet, (sometimes Red-fronted Parakeet) Cyanoramphus novaezelandiae, is a small species of parrot from New Zealand. The species was once lumped with several other parrots from New Zealand's outlying islands, New Caledonia and Norfolk Island, but these have now been afforded full species status.[1] The species is one of three New Zealand parakeet species known by the Māori name kākāriki.

Red-crowned Parakeets feed on seeds, fruit, berries, nuts and other parts of plants.

The Red-crowned Parakeet was once widespread across the islands and mainland of New Zealand. It was extremely abundant during the 1880s and irruptions occurred in a number of locations. It is currently extinct on the mainland of New Zealand and is confined to Stewart Island/Rakiura and a number of offshore islands (such as Kapiti Island, Tiritiri Matangi Island[2] and Matiu/Somes Island) as well as the Kermadec Islands to the north of New Zealand, on the Auckland Islands to the south and the Chatham Islands to the east. The two island populations are sometimes afforded subspecific status. They are considered vulnerable by the IUCN and BirdLife International because the remaining populations are highly fragmented.[3] Their extinction on the mainland was due to their vulnerability to introduced species, particularly stoats, rats and possums.

Aviculture

The Red-crowned Parakeet is common in aviculture and is relatively easy to breed. Several colour mutations are available including, yellow, cinnamon and piebald.

The Kermadec Red-crowned Parakeet (Cyanoramphus novaezelandiae cyanurus), also known as the Kermadec Red-fronted Parakeet or Kermadec Parakeet, is a parrot endemic to New Zealand's Kermadec Islands in the south-west Pacific Ocean. It is a subspecies of the Red-fronted Parakeet, and sometimes considered a full species. It is also the first documented example of a parrot recolonising an island after the removal of invasive predators.[2]

Description

The Kermadec Red-crowned Parakeet is a medium-sized, predominantly green parrot with a crimson cap and eye-stripe. At about 29 cm in length, and 80-90 g in weight, it is significantly larger than the nominate subspecies, as well as having noticeably bluer plumage.[3][4]

Distribution

The parakeet is found in the Kermadec group, which lies about 1000 km NNE of New Zealand's North Island, and 900 km SSW of Tongas 'Ata Island. However, it was eradicated from the principal island in the group, 30 km2 Raoul, in the early 19th century, with the last records of breeding there in 1836, as a consequence of the introduction by humans of goats, cats, and both Brown and Polynesian Rats. It survived only on the nearby Herald Islets 2–4 km away, where there are about 50 breeding pairs, and on 3 km2 Macauley Island some 100 km to the south with about 10,000 breeding pairs.[2]

For 172 years no breeding was recorded on Raoul, although occasional vagrant individual birds were seen. In 2008, following island restoration that included the removal of goats by 1986, the rats by 2004 and the cats by 2006, Red-crowned Parakeets were again recorded breeding on Raoul Island, presumably having recolonised it from the Herald Islets.[2]

Behaviour

The parakeets are normally seen in pairs or small groups outside the breeding season. They may form flocks, though some pairs remain alone through the year. They forage on or near the ground, congregating at water sources to drink and bathe. Flocks will occasionally fly to neighbouring islands to forage.[4]
